Abstract: PURPOSE:To contrive to improve a throughput capacity by equipping a pusher for moving a substrate-containing jig at the lowermost level outward of a first or second movable mount. CONSTITUTION:At the same time that a first movable mount 13a drops at the same distance as the height dimension Ha of a substrate-containing jig 11, a stopper 12 operates to hold the second lowest substrate-containing jig 11 and thereafter temporarily. After that, a pusher 15 operates to move the lowermost substrate-containing jig 11 left on the first movable mount 13a outward of the first movable mount 13a, which moves transversely immediately thereafter. Simultaneously, when the second movable mount 13b moves in the opposite direction to and at the same distance as the movement of the first movable mount 13a and is positioned directly under and in the vicinity of the substrate-containing jig 11 held temporarily by the stopper 12, the stopper 12 releases holding the substrate-containing jig 11 and places a plurality of piled substrate-containing jigs 11 on the second movable mount 13.

Title: Semiconductor integrated circuit
IPC: H03K17/16
Filed: 1991-02-05
Abstract: PURPOSE:To reduce ringing and to increase the operation speed by providing a potential fixing means to fix the high level potential of inverters, which are circuits preceding and following an output circuit, to a prescribed potential. CONSTITUTION:A ring oscillating. circuit 12, a voltage generating circuit 25, and an N-type MOST 24 realize a potential fixing means M1. The circuit consisting of the ring oscillating circuit 12 and the voltage generating circuit 25 gives a certain voltage (0.9VX6=5.4V) as the threshold voltage of MOSTs 17 to 22. That is, a value obtained by multiplying the threshold voltage of MOSTs 17 to 22 by 6 (the number of MOSTs) is outputted to an output line 23, and the certain voltage (5.4V) is generated independently of the variance of a supply potential Vcc. This voltage is reduced in an MOST 24 in the succeeding stage by its threshold voltage (0.9V) to give the level of 5.4V-0.9V=4.5V to a node N1. The transistor width or the like of an MOST 8 constituting an inverter 3 is so adjusted that the ringing level of DOUT is lower than a prescribed value (0.4V) on this condition.

Abstract: PURPOSE: To realize a high speed and large capacity with an inexpensive general HDD by instructing seek operation to all of plural hard disk drives(HDD) based on access information, selecting the specified HDD and making it perform write-in/read-out. CONSTITUTION: A control instruction circuit 1 imparts seek instruction 22, 25 to all HDDs 3, 4 respectively when it receives the seek instruction 11 from a host device. Then, the circuit 1 analyzes head address information 12, and selects either one of the first, second HDDs 3, 4 according to e.g. an odd/an even, and sends the head address information 30 or 31 to them. Further, the circuit 1 sends a switch signal 17 to a write-in/read-out switch circuit 2, and instructs the connection to either one of the selected HDDs 3, 4. The write-in/ read-out is performed by either one of the selected HDDs 3, 4 through the write-in/read-out switch circuit 2 according to the write-in or the read-out of the instruction from the host device. Since the write-in/read-out is performed continuously ranging to respective HDDs, a seek time is saved.

Title: Production of solid sorbitol
Inventor: KUNIMI YUJI
IPC: C07C29/78
Filed: 1988-02-20
Abstract: PURPOSE:To obtain the above substance by adjusting molten sorbitol to a temperature to keep the molten sorbitol from solidification and a seed crystal from melting, adding and dispersing a seed crystal to the molten sorbitol under stirring, solidifying the melt by the primary cooling at a specific temperature, keeping in the state over a prescribed period and subjecting to secondary cooling. CONSTITUTION:Molten sorbitol is adjusted to a temperature (e.g., 70-90 deg.C) to keep the molten sorbitol from solidification and a seed crystal from melting. A seed crystal is added to and dispersed in the molten sorbitol in an amount of 1-50wt.% under stirring. The molten mixture is solidified by the primary cooling at 50-85 deg.C, maintained at the temperature for a prescribed period (e.g., >=5min) and subjected to secondary cooling, e.g., by quenching to obtain the objective substance. The seed crystal is crystalline sorbitol which may contain fats and oils (e.g., vegetable oil or animal oil) and/or surfactants (e.g., glycerol fatty acid ester). It is preferable to add the fats and oils and/or surfac tant to molten sorbitol to prevent the local temperature lowering of the molten sorbitol caused by the addition of the seed crystal and troubles caused by the temperature lowering.
